Contostavlos also admitted that her judging style is very varied, joking that she can be both nasty and nice because of her "split personality".

"I've been cruel at times; I've also been very nice and very emotional sometimes," she explained. "I mean, it's pretty much a split personality with me. I'm a Cancerian - so a hard outer shell but a soft center."
